Ok, so maybe all snakes do this but I only notice it on Willow because she's all white, but when we hold her, sometimes we will find the odd scale, or small patch, that looks.... indented? bent? flipped? Then she does her snake slither and in a while the scales are normal. They aren't flaked out but almost indented.
Are they just resting oddly and when she moves they flatten out? It's so weird!!
